Your system is older, and these newer games are exposing the deficiencies. The Phenom II was new back in 2010.
If you have the money, an Intel Core i5 is a great processor for gaming. If you want a more budget build, AMD FX8350 or 8320 are viable options.
Ok awesome I was trying to hold on to a last hope that there might be a software issue but I guess it's time for an upgrade.
Thank you for your time
